Trending plot for CRIRES RON as determined from DARK exposures.
The read-out noise is measured from the difference of the 3rd and 2nd dark
image using the following procedure:
- generate 100 13x13 pixel windows
- compute the pixel standard deviation in each window
- the read-out noise is the median of these measurements multiplied with
sqrt(NDIT/2).
The trending shows RON from DIT=1sec and DIT=300sec exposures for all
four chips.
General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
